New Guinea Impatiens plant named ‘Odyparnassus’

Abstract

A new and distinct cultivar of New Guinea Impatiens plant named ‘Odyparnassus’, characterized by its upright, outwardly spreading and vigorous growth habit; freely branching and freely flowering habit; dark green-colored foliage; large, rounded, pink-colored flowers; and flowers that are positioned above or beyond the foliage.

Description

Botanical designation: Impatiens hawkeri.

Cultivar denomination: ‘Odyparnassus’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, and hereinafter referred to by the name ‘Odyparnassus’.

The new Impatiens is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program was to create New Guinea Impatiens with large flowers, attractive flower coloration, good postproduction longevity and drought tolerance.

The new New Guinea Impatiens originated from a cross-pollination conducted in Aalsmeer, The Netherlands on May 16, 2001 of a proprietary selection of New Guinea Impatiens identified as code number 99023, not patented, as the female, or seed, parent with a proprietary selection of New Guinea Impatiens identified as code number 99015, not patented, as the male, or pollen, parent, The cultivar Odyparnassus was discovered and selected by the Inventor as a single plant within the progeny of the stated cross-pollination in a controlled environment in Aalsmeer, The Netherlands on Sep. 30, 2001.

Asexual reproduction of the new cultivar by terminal cuttings in Aalsmeer, The Netherlands since Feb. 17, 2002, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Odyparnassus’. These characteristics in combination distinguish ‘Odyparnassus’ as a new and distinct Impatiens cultivar:

• • 1. Upright, outwardly spreading and vigorous growth habit.
  • 2. Freely branching and freely flowering habit.
  • 3. Dark green-colored foliage.
  • 4. Large, rounded, pink-colored flowers.
  • 5. Flowers that are positioned above or beyond the foliage.

Plants of the new Impatiens can be compared to plants of the female parent selection. In side-by-side comparisons conducted by the Inventor in Aalsmeer, The Netherlands, plants of the new Impatiens differed from plants of the female parent selection primarily in flower coloration as plants of the female parent selection had red-colored flowers. In addition plants of the new Impatiens had smaller leaves than plants of the female parent selection.

Plants of the new Impatiens can be compared to plants of the male parent selection. In side-by-side comparisons conducted by the Inventor in Aalsmeer, The Netherlands, plants of the new Impatiens differed from plants of the male parent selection primarily in flower coloration as plants of the male parent selection had pink and white bi-colored flowers.

Plants of the new Impatiens can also be compared to plants of the cultivar Neptis, disclosed in U.S. Plant Pat. No. 10,321. In side-by-side comparisons conducted by the Inventor in Aalsmeer, The Netherlands, plants of the new Impatiens differed from plants of the cultivar Neptis in the following characteristics:

• • 1. Plants of the new Impatiens were not as broad as plants of the cultivar Neptis.
  • 2. Plants of the new Impatiens had shorter internodes than plants of the cultivar Neptis.
  • 3. Plants of the new Impatiens had narrower leaves with smaller petioles than plants of the cultivar Neptis.
  • 4. Plants of the new Impatiens were more freely flowering than plants of the cultivar Neptis.
  • 5. Plants of the new Impatiens and the cultivar Neptis differed in flower coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Impatiens. The photograph comprises a side perspective view of a typical flowering plant of ‘Odyparnassus’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The cultivar Odyparnassus has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The aforementioned photograph, following observations and measurements describe plants grown during the fall in De Kwakel, The Netherlands, under commercial production practice in a glass-covered greenhouse. Rooted young plants were planted in 13-cm containers and the aforementioned photograph and following observations and measurements were taken about 14 weeks later. During the production of the plants, day and night temperatures averaged 18° C. and light levels were about 200 W/m². In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
